A carrier head for chemical mechanical polishing, includes a base, a support structure attached to the base having a surface for contacting a substrate, and a retaining structure attached to the base to prevent the substrate from moving along the surface. The retaining structure and the surface define a cavity for receiving the substrate. The retaining structure includes an upper portion in contact with the base, a lower portion, and a vibration damper separating the upper portion and the lower portion. The vibration damper, the vibration damper includes a material that does not rebound to its original shape when subjected to a deformation.

In a first aspect, a first method of drying a substrate is provided. The first method includes the steps of (1) lifting a substrate through an air/fluid interface at a first rate; (2) directing a drying vapor at the air/fluid interface during lifting of the substrate; and (3) while a portion of the substrate remains in the air/fluid interface, reducing a rate at which a remainder of the substrate is lifted through the air/fluid interface to a second rate. The drying vapor may form an angle of about 23° with the air/fluid interface and/or the second rate may be about 2.5 mm/sec.

A chemical mechanical polishing apparatus has a polishing surface, a carrier head to press a substrate against the polishing surface with a controllable pressure, a motor to generate relative motion between the polishing surface and the carrier head at a velocity, and a controller. The controller is configured to vary at least one of the pressure and velocity in response to a signal that depends on the friction between the substrate and the polishing surface to maintain a constant torque, frictional force, or coefficient of friction.

A selective Damascene chemical mechanical polishing (CMP) technique is used to planarize a semiconductor device to remove surface topography. The semiconductor device includes a semiconductor layer formed on a substrate, an insulating layer formed over the semiconductor layer and patterned to expose a portion of the semiconductor layer, a barrier layer formed over the insulating layer and the exposed portion of the semiconductor layer, and an electrically conductive layer formed over the barrier layer. The semiconductor device is pressed against a first rotating polishing pad that has no embedded abrasive particles to remove a portion of the conductive layer that overlies both the barrier layer and the insulating layer. The semiconductor device is then pressed against a second rotating polishing pad that has embedded abrasive particles to expose a portion of the barrier layer that overlies the insulating layer. The device is then pressed against a third rotating polishing pad that has no embedded abrasive particles to remove the portion of the barrier layer that overlies the insulating layer.
